第 6 題
6.下列何者於使用含有血管收縮藥物的局部麻醉劑時,要特別衡量其益處及風險?①甲狀腺功能障礙 ②對亞硫酸鹽(sulfite)過敏 ③使用三環類抗憂鬱藥 ④心血管疾病處於 ASA 3 級和 4 級
- A 僅①③
- B 僅②③④
- C 僅①②④
- D ①②③④
思路引導 VIP
請從臨床藥理學的角度出發,思考局部麻醉藥中添加血管收縮劑(如 $Epinephrine$)的目的與伴隨的化學成分。首先,為了穩定該收縮劑,藥液中必須添加哪種可能誘發特定族群過敏反應的抗氧化劑?其次,血管收縮劑作為擬交感神經藥物,對於甲狀腺功能異常、心血管儲備能力不足(如 $ASA\ 3$ 或 $4$ 級)以及正在服用會抑制神經傳導物質回收藥物(如 $Tricyclic\ Antidepressants$)的患者,分別會透過何種藥理生理機制或交互作用顯著增加全身性的風險?
